URL shortcuts is a free Chrome add-on developed by 1978milan.babic. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory. This handy tool provides shortcut and autosuggestions for URLs, making it incredibly convenient for web developers.

The main purpose of URL shortcuts is to assist developers who frequently use similar URLs but with different pages within the same domain. By allowing users to create a working project base URL, the add-on saves time and effort. Users can edit a list of shortcuts and when they search for a suggested URL, the add-on generates a modified link.

When users open the extension for the first time, they can create their project's base URL using existing shortcuts or by manually entering it. The browser automatically opens a new tab with the base URL. The next time the extension is opened, the project's base URL is already set, allowing users to easily open pages related to that project.

If users enter a URL that is not on the extension's list, the add-on remembers that part of the URL and saves it as a suggestion for future browsing. Changing the project's base URL is simple - users can press the escape button when focused on the input field.

Overall, URL shortcuts is a useful tool that speeds up the development process for web developers. To ensure optimal performance, it is recommended to create a shortcut on the browser's plugins page, as shown in the provided introductory image.
